Connect Four rules

Simple rules, devious possibilities. Here’s everything you need to beat BittsBot, or at least make it work for the win.

The goal

Be the first to line up four of your discs in a row , across, up, or on a diagonal. You play against BittsBot, and you each drop one disc per turn.

Taking a turn

Pick a column and your disc drops into the lowest open slot, gravity does the rest. You can’t place a disc mid-air, and a full column locks itself. BittsBot answers right after you, then it’s your move again.
